To all whom it mag/concern:

Be it known that I, JAMES T01), of Se- Wickley,in the county. ofAllegheny and State of Pennsylvania, have invented anew ducing So-CalledOzonized Air, of which the following is a full, clear, and exactdescription, referencebeing had to the accomspecification, in which thefigure is a side elevation of one form of apparatus for car-,,

rying out my invention.

Heretofore in the operation of ozone maamount of air passing to .theozonizing machine to compensate for the changes brought about by thechanges of the temperature of the surrounding atmosphere, from which theair is drawn to pass through the machines.

I have discovered that with the same ozone machine, a certain strengthof gas will-be given at a relatively low atmospheric temperature, whilewith the same amount of air at a relatively higher'atmospheric temperature, the ozone constituent of the tread air will, almost disappear. Inother words, I have found that the strength of the socalled ozonized airvaries with thetemperature of the atmosphere'from which it is drawn. Forexample, a given quantity of air drawninto the ozonizer at 15 0., willgive a certain strength of the so-called ozonized air, while at atemperature of 18 to 20 (1, for the external air, this gas or ozonizedair is much weaker, and at a temperatu of 28 or- 30 C. in the externalatmosphere, the so-called ozone constituent has almost disappeared. Ihave also discovered that I can greatly reduce or overcome this greatvariation in the ozone percentage by decreasing the quantity of airpassed through the ozonizer as the temperature of the atmosphere rises,and increasing the quantity of air as the temperature of the atmospherefalls.

Of course, many different kinds of apparatus may be used for obtainingthe desired result. For example, as shown in my drawings, the engine oractuating shaft 2 may be provided with a stepped cone pulley "3, hav-.ing a belt leading to a similar reversed or stepped cone pulley thou theshaft 5, which is provided with mpul 6, having a belt leading to asimilar pulley on the shaft 7 of the blower 8, for supplging air to theozonizer 9 having a pipe I leading therefrom. this arrangement, as thetemperature rises, the operator will shift the Y .belt to successivelysmaller pulleyson the engine shaft, so as to decrease the speed of theblower and thereby decrease the amount of air passing to the so-calledozone machine. f Of course, many other forms of change gear devices maybe used, and' instead of using a chan e gear device, I may simplyprovide a valve for the air supply to the -ozonizer, which valve will begradually closed as the-temperature rises, thus similarly decreasing theamount of air'coming to the ozone machine. Of course, a thermoa staticdevice may be provided, which will automatically decrease the amount ofair as the temperature rises, and increase it as the temperature falls,but in my experiments on the subject, I have simply used a handoperateddevice which ,will provide for .iis variation in the air supplyaccording the temperature. The 9.11 may be awn through the machineinstead of forced through it.

The advantages of my invention will be obvious to thoseskilled'in theart, since it provides a method for obtaining an ooni ized air of a muchmore uniform character than was before possible. Heretofore, the

strength or character of the gas has varied very greatly as thetemperature of the surrounding atmosphere varied, while the reason forthese changes in its strength has not been understood. My discoveryprovides for obtaining a comparatively regular or uniform character ofthis so-called ozonized air,-thereby enabling uniform results to beobtained from itsuse.

I claim:

-1; In the manufacture of so-called ozonized air, the step consisting ofvarying the amount 'of air passing to the ozonizer according to thetemperature of the surrounding atmosphere, substantially as described.

.2. In the manufacture of so-called ozonized'air, the step consisting inreducing the amount of air passing to the ozonizer as the temperaturerises, substantially as described.

3. In the manufacture of so-called ozonized air, the step consisting inincreasin the amount of air passing to the ozone madliine as thetemperature falls, substantially as de scribed.

4. In the manufacture of so-called ozonized air, the method consisting.in varying creasing it as the temperature falls, substan-.

tially as described.

5. In the manufacture of so-ca lled ozonized alr, the step consisting ofvarylng the amountof an" passing to the ozonlzer, and

lo reducing the amount of air as the temperature rises but increasingthe amount of air as the temperature falls substantially as described. v

' In testimony whereof, Ihave hereunto set my hand.
